RUDDER MOTOR STERN PLANE MOTOR COILS PERISCOPE MISSILE TUBES PROPULSIONMOTOR INVENTOR RICHARD E. DIAS BY M AGENT United States Patent 3,229,420REMOTELY CONTROLLED, ELECTRICALLY OPERATED, MODEL SUBMARINE Richard E.Dias, 17 E. Emerson Sh, Melrose 76, Mass. Filed Nov. 27, 1962, Ser. No.240,466 6 Claims. (Cl. 46-244) (Granted under Title 35, US. Code (1952),sec. 266) The invention described herein may be manufactured and used byor for the Government of the United States of America for governmentalpurposes Without the payment of any royalties thereon or therefor.

This invention relates to a nautical amusement device, and moreparticularly it relates to a remotely controlled model submarine of themissile launching type.

While models of the type herein disclosed are used primarily as toys,their use is not limited to such and they can be of considerable valueas educational devices for acquainting personnel with the operationalcharacteristics of vessels of the type simulated by the models.

Accordingly, an object of this invention is to provide a model submarinewhich is remotely controlled, which is a simulacrum of an actualsubmarine and which is capable of performing both its surface andsubmerged operations.

Another object of this invention is to provide a model submarine havingself-contained steering equipment whereby the operator of the remotecontrol can cause the submarine to follow any course he chooses.

A further object of this invention is to provide a model submarinecapable of carrying novel miniature missiles and of firing the same upona command from the operator.

Other objects, advantages and salient features of the present inventionwill become apparent from the following description, taken in connectionwith the accompanying drawings, which illustrate a preferred embodiment,in which:

FIG. 1 is a perspective view of a model submarine in accordance with thepresent invention.

FIGS. 2A and 2B are a vertical longitudinal sectional view of the modelsubmarine;

FIG. 3 is a transverse sectional view taken along the plane indicated bythe line 3-3 of FIG. 2A and illustrating details of the tail section ofthe model submarine;

FIG. 4 is a block diagram of the control system for the variousoperating components of the model submarine;

FIGS. 5A and 5B are a schematic wiring diagram of the control panel forthe model submarine;

FIG. 6 is a diagrammatic view of the wiring between the control paneland the various components on the model submarine; and

FIGS. 7, 8 and 9 are different embodiments of missiles which are firedfrom the model submarine.

Referring now to FIG. 1, a model submarine in accordance with thepresent invention is shown floating in a body of water which ishereinafter arbitrarily referred to as the sea or sea water, although itis to be understood that submarine 20 may be used in any lake, river,model tank or other suitable body of water. The model submarine 20 iscomprised of a main hull portion 22, an upper hull portion 24 and a sailmeans 26 mounted one upon the other as is illustrated in FIG. 1. Balsawood, glass reinforced plastic or other suitable materials can be usedfor constructing the exterior of the submarine.

A propeller means 28 provides propulsion for the submarine. Motion ofthe submarine is controlled by sail planes 30, stern planes 32 andrudder means 34. The sail 26 includes a slidably movable periscope means36 and a rotatable radar mast 38.

Both running lights and anchor lights are provided on the model. Therunning lights are comprised of a masthead light 40 on the forward partof the sail 26, a port light (not shown) on the port side of the sail26, a starboard light 42 on the starboard side of the sail 26 directlyopposite the port light and an emergency stern light 44 on the rear partof the sail 26. The anchor lights are comprised of a forward light 46 onthe aft of the hull 22, a sail light located within the sail 26 butvisible through plastic windows 48, a stern light 50 on the sternportion of the upper hull 24 and a rudder light 52 on the upper portionof the rudder means 34.

Other features which are illustrated on the model of FIG. 1 are dummytorpedo tubes 54, a forward ballast tank flood port 56 and vent 58, anafter ballast flood port 60 and vent 62, six missile tubes generallyindicated as 64 and access holes 66 for the missile tubes. Though thetorpedo tubes 54 are indicated as dummy tubes, it is possible, ifdesired, to provide doors thereon and provide tube means which areadapted to fire torpedoes in much the same manner as will be presentlydescribed for the firing of missiles. With the exception of the dummytubes 54, all hardware and accessories shown in FIG. 1 are operative. Itis possible to provide numerous non-operating accessories such as radioantennas and the like in order to more closely simulate the appearanceof an actual submarine, and such accessories have not been shown sincethey merely constitute design features rather than an integral part ofthe present invention.

The model submarine 20 of FIG. 1 is shown firing a missile from one ofthe missile tubes 64. The particular construction of the missile will bepresently described, but at this point it can be stated that the missileis of a type which simulates the Polaris missile and which can be firedeither from a submerged position or from a surface position. Power tomaneuver the model submarine 20 and to fire the missiles is supplied byan electrically conducting cable means 70 which connects to a controlmeans 72 in the form of a control panel.

Referring now to FIG. 2A, it can be seen that the propeller 28 whichpropels the submarine 20 is mounted on the end of a main shaft 74 whichconnects through a flexible coupling 76 to a propulsion motor 78. Thepropulsion motor 78 is a reversible, variable speed DC. motor of theseries shunt type. The shaft 74 is rotatably mounted within a tubularhousing 80 by means of a plurality of roller bearings 82 located atspaced intervals along the interior of the housing. End bushings 84 and86 are provided at opposite ends of the housing means 80 to enclose thebearings 82 and render them relatively isolated from impurities. Theoutermost end bushing 86 has a groove therein containing a shaftsurrounding O-ring 83 to insure that the interior of the housing means80 will be watertight. An O-ring housing 90 with a plurality of O-rings92 contained therein is located adjacent the end bushing 36 to furtherinsure watertight integrity. Finally, a rubber seal means 94 is locatedbetween the outer end of the O-ring housing 90 and the propeller means28. This seal 94 has the function of further rendering the inte rior ofthe submarine 20 watertight.

Rotational movement of the rudders 34 is controlled by a rudder motor96, of the reversible D.C. type. The upper and lower rudders areinterconnected by means of a shaft 98 which is elbowed around the mainshaft housing 80 in a manner which can best be seen in FIG. 3. Rubberseal means 100 surround the shaft 98 beneath each of the rudder for thepurpose of preventing entry of water into the submarine through theshaft apertures. The rudder motor 96 has a drive gear 102 which engagesand drives a bull gear 104 mounted on the inner end of a shaft 106. Adrive gear 108 is provided on the outer end of the shaft 106 to drive anidler or connecting gear 110 which in turn drives a sector gear 112which is affixed to the rudder shaft 98. The rudder shaft passes througha pair of roller bearings 114 mounted in the hull near the seal means188. The effect of the gear train is that the drive motor 96 rotates theshaft 98 to turn the rudders 34 angularly to the right or to the left,depending on which direction the motor 96 is operating.

Rotational movement of the stern planes 32 is controlled by a sternplane motor 116, of the reversible D.C. type, which is shown in FIG. 3.The two planes 32 are interconnected by a shaft 118 which is elbowedaround the main shaft 80 in a manner similar to that of the shaft 98.The shaft 118 is provided with rubber seal means similar to seal means100 for the rudders. The stern plane motor is provided with a drive gear120 which en gages a sector gear 122 which is afiixed to the shaft 118.Thus, as the stern plane motor 116 operates, the gears 120 and 122 willturn the shaft 118 to make the planes 32 assume either as rise or a diveposition, depending upon which direction the motor 116 is operating.

The model submarine is provided with a plurality of missile tubes 64which are shown as two rows of three tubes each, thus making a total ofsix missile tubes. The tubes themselves are each formed of an elongatedtubular member 130 which has a heat producing means 132 threaded intoits lower portion. A suitable heat producing means 132 has been found tobe a model airplane Glo-plug which, when energized by electrical currentgives ofi a considerable amount of heat. Each tubular member 130 isprovided with a tube door 133 which is turn is provided with a tensionspring means 134 to maintain the door in its open position once it hasbeen manually opened. The door 133 when closed bears against a suitablesealing means such as a gasket 136 to prevent water entry into thetubular member 138. Each tubular member 130 has an upper portion 138which. extends slightly above the hull. This allows the operator toplace a rubber diaphragm over the portion 138 and attach it by means ofa wire or rubber band, thus rendering the missile tube watertight evenwhen submerged with the door 133 open. This allows launching of amissile even when submerged without allowing the missile to become wetbefore firing. The lower portions of the missile tubes 64 can beindividually plugged or can be sealed by some common means such as ahinged door (not shown).

The radar mast 38 and its operating mechanism are located either withinthe sail 26 or directly below it, and can best be seen in FIG. 2B. Themast 38 is an elongated rod having a replica of a radar antenna at itsupper end. The central portion of the mast 38 is housed within a tubularmember 140. A fitting 142 surrounds the lower end of the mast 38 isprovided with a pair of bearings 144. Another bearing 144 is providednear the upper end of the mast 38. A rubber seal means 146 surrounds themast 38 where it passes through the hull to provide watertightintegrity. Additional leakage preventing means in the form of an O-ringhousing 148 and a plurality of mast surrounding O-ring 158 is providedadjacent the inner side of seal means 146.

The radar antenna can be trained in either direction by rotation of themast 38. This rotation is provided by means of a radar motor 152 of thereversible D.C. type. The radar motor 152 has a drive gear 154- whichengages a larger gear 156 which is affixed to the mast 38; thus rotationof the motor 152 in one direction will cause rotation of the radar mast38 and antenna in the opposite direction.

The periscope 36 is an elongated rod which passes through the hull inthe sail 26 forward of the radar mast 38. Rubber seal means 160 and anO-ring housing 162 with periscope surrounding O-rings 164 assurewatertight integrity. The central portion of the periscope 36 is housedwithin a tubular member 166, having an internal shoulder 168. The lowerportion of the periscope 36 is wider than the upper portion therebyproviding a shoulder 170. A coil compression spring 172 surrounds theperiscope 36 and is mounted between the shoulders 168 and 170. Theperiscope 36 is raised and lowered by means of electromagnetic coils 174and 176 which are connected in parallel. The lower portion of theperiscope below the shoulder acts at the slug for these coils. Thus,when the coils are actuated, the periscope 36 is raised. When power tothe coils is cut off, the compression spring 172 and gravity cause theperiscope to lower. It is possible, if desired, to provide suitablelocking means for locking the periscope 36 in its raised position, suchas for example, by rotating the periscope manually to a locked position.

The sail planes 30 are operated in a manner similar to the stern planes32. The planes 30 are interconnected by a shaft 180 which is sealed in amanner similar to that of the stern plane shaft 118. The operatingmechanism for the sail planes 30 is shown in FIG. 2B. It consists of asail plane motor 182 of the reversible D.C. type, which is provided witha drive gear in the form of a worm 184. The worm 184 mates with a drivegear 186 which is aflixed to the shaft 180. Thus, rotation of the sailplane motor 182 causes rotation of the sail planes 30.

The model submarine 20 has a forward ballast tank 198 and an aft ballasttank 192, said tanks cooperating to control the overall ballast of themodel. When the model is placed in the water, water starts to enter theballast tanks through their flood ports 56 and 68, thus forc ing air outthrough the vents 58 and 62. When the operator determines that properbuoyancy has been reached, he plugs the ports 56 and 60 with somesuitable plug means such as corks. Depending upon the size and weight ofthe model, and the depth desired, it may be necessary to also plug thevents 58 and 62. Because of the size and weight variables, control ofthe ballast of a model becomes a matter of trial and error until theoperator becomes sufficiently familiar with the operationalcharacteristics of his model.

As can be seen from FIG. 2B, the electrically conductive cable means 70enters the lower portion of the hull 22 of the model submarine 20. Arubber seal means 194 surrounds the cable means 70 to assure that nowater will leak along the cable and into the interior of the submarine.

FIG. 4 illustrates in block diagram form, the path of the power from thepower supply through the control panel 70 to the model submarine 20. Thespecific circuitry for the model is shown in FIGS. 5A and 5B. The powersupply, as seen in FIG. 5A is a 12.0-volt, 60-cycle, A.C. source whichis connected to a conventional stepdown transformer 200. The outputlines from the transformer 208 comprise two lines 202 and 204 whichcarry 35 volts, a line 206 which carries 28 volts, a line 208 whichcarries 26 volts, a line 210 which carries 24 volts, a line 212 whichcarries 22 volts and a common line 214. t 1

Power for controlling the propulsion motor 78 is tapped off the 35-voltlines 202 and 284 to an isolation switch 216 of the conventional doublepole, double throw type which in turn connects to the A.C. terminals ofa conventional full wave bridge rectifier 218, which is also identifiedas rectifier A. A conventional double pole, double throw switch 220 isconnected to the D.C. terminals of the rectifier 218 to thereby controlpower to the propulsion motor 78. The switch 220 is connected to aterminal block 222, which is also identified as TB3, by means of fourleads. Leads 224 and 226 connect to terminals 7 and 8 respectively ofTB3 and these leads supply power to the armature circuit of the motor78. Leads 228 and 230 connect to terminals 9 and 10 respectively of T83and these leads supply power to the field circuit of the motor 78. Twoindicating lights are connected between the rectifier 218 and the switch220 to indicate whether the motor 78 is propelling the model forward orbackward.

The planes, radar and rudder, are controlled by 22 volts of power whichis tapped oil line 212 to an isolation switch 232 of the conventionalsingle throw, double pole type which in turn connects to the AC.terminals of a conventional full wave bridge rectifier 234, which isalso identified as rectifier B. The two leads from the DC. terminals ofthe rectifier 234 supply power to switches for controlling the sailplanes, stern planes, radar, and rudders. These switches are all of thedouble pole, double throw type having crossed diagonal terminals and allthe switches are connected in parallel with the DC. leads from rectifierB. An indicating lamp 236 is also connected in parallel with the DC.terminals to indicate when the rectifier B is receiving power.

One of the above-mentioned switches is switch 238 which controls powerto the rudder motor 96. This switch is connected by leads 240 and 242 toterminals 5 and 6 respectively of a terminal block 244 which is alsoidentified as TB2. A pair of indicating lights are also provided at theswitch 238 to indicate whether the rudder motor 96 is turning therudders 34 right or left.

Another of the above-mentioned switches is switch 246 which controlspower to the stern plane motor 116. This switch is connected by leads248 and 250 to terminals 1 and 2 respectively of T132. A pair ofindicating lights are also provided at the switch 246 to indicatewhether the stern plane motor 116 is moving the stern planes 32 to arise or drive position.

Another of the above-mentioned switches is 252 which controls power tothe sail plane motor 182. This switch is connected by leads 254 and 256to terminals 3 and 4 respectively of TB2. A pair of indicating lightsare also provided at the switch 252 to indicate whether the sail planemotor 182 is moving the sail planes 30 to a rise or a dive position.

The last of the abov-mentioned switches is switch 258 which controlspower to the radar motor 152. This switch is connected by leads 260 and262 to terminals 7 and 8 respectively of TB2. A pair of indicatinglights are also provided at the switch 258 to indicate whether the radarmotor 152 is turning the radar mast 38 right or left. A variableresistance 264 of 8 to ohms can be provided in the lead 262 to vary thespeed of rotation of the radar mast 38.

Power for controlling the periscope coils 174 and 176 is tapped off the35-volt lines 202 and 204 to an isolation switch 266 of the conventionalsingle throw, double pole type which in turn connects to the AC.terminals of a conventional full wave bridge rectifier 268, which isalso identified as rectifier C. A crossed-diagonal double pole, doublethrow switch 278, of the type described hereinabove, is connected to theDC. terminals of the rectifier 268. The switch is connected by a pair ofleads 272 and 274 to terminals 9 and 10 respectively of TB2. Anindicating light is connected across the leads 272 and 274 to indicatewhen the coils 174 and 176 are moving the periscope 36 to a raisedposition.

The model submarine can be run at various speeds since the mainpropulsion motor 78 is a variable speed motor. The different speeds areaccomplished by means of a rheostat 276 which connects to a speedselector switch 278. The speed selector switch 278 is connected to thelines 204 through 212 inclusive. Standard speed is indicated on theswitch as I which corresponds to 26 volts. Similarly full speed or II is28 volts, flank speed or III is 35 volts, /3 speed is 22 volts and speedis 24 volts. A conventional single pole, double throw switch 280 is usedto connect the rheostat to the main motor circuit.

When the switch 280 is swung to its other position, it deactivates thespeed control from the main motor circuit and activates the fire controlcircuit by connecting a lead 282 from one of the DC. terminals ofrectifier B to another lead 284 which leads to a conventional singlethrow, double pole switch 286 which acts as a fire control isolationswitch. A lead 288 connects the other D.C. terminal of rectifier B withthe other pole of the isolation switch 286. The fire control isolationswitch and the rest of the fire control circuit, as well as the lightingcontrol circuit are shown in FIG. 5B.

A lead 289 connects negative terminal of the fire control isolationswitch 286 to terminal 7 of a terminal block 290, which is alsoidentified as TBl. To prevent accidental firing of a loaded missiletube, a safety circuit has been included as part of the firing circuit.The safety circuit comprises a series of six push-buttons generallyindicated as 291 and a three tier selector switch having selectorportions 292, 294, and 296. A lead 298 connects the positive terminal ofthe switch 286 to one side of each of the push-buttons 291, to oneterminal of a spring-loaded firing button 300 and finally to the centertap of the lower selector switch portion 292. The other side of each ofthe push-buttons 291 connects to a terminal on switch portion 292 whichcorresponds to the missile tube number. For example, push-button #6 isconnected to terminal #6 on switch portion 292 to control the firing ofmissile tube #6.

The other terminal of the firing button 300 connects to the center tapof the upper switch portion 294. This switch portion has terminalsnumbered 1 through 6 which are connected to terminals 1 through 6respectively of TB1 by means of leads 302, 304, 306, 308, 310 and 312respectively.

Indication of which tube is being fired is provided by a group of sixindication lights generally designated as 314. One side of each of theselights connects to a lead 316 which taps oif the 22 volt line 212. Theother side of each of the lights connects to the terminals on the switchselector portion 294. The center tap of portion 294 is supplied with 24volts by means of a lead 318 which taps off the line 210. The net resultis that two volts of power are supplied to whichever of the lights theoperator selects on switch portion 294.

A lamp 320, which indicates that the fire control circuit is beingsupplied with power, is connected between the leads 289 and 298. Thislamp 320 will be lit when switch 280 is closed to the fire controlposition and when switch 286 is closed.

Lighting controls for the model submarine 20 are provided by a pair ofsingle throw, double pole switches which are tapped oh" the transformerlines. The anchor lights switch 322 is tapped ed the 22-volt line 212and the 26-volt line 208 and it thus supplies 4 volts to the anchorlights. The switch 322 is connected by leads 324 and 326 to terminals 8and 10 respectively of Till. The running lights switch 328 is tapped offthe 22-volt line 212 and the 28-volt line 206 and it thus supplies 6volts to the running lights. The switch 328 is connected by leads 330and 332 to terminals 9 and 10 respectively of TBI. It is thus seen thatterminal 10 of TB1 is common to both the running lights and the anchorlights. The lead running from terminal 10 to the lights will arbitrarilybe referred to hereinafter as 326, only, although it is understood thatit receives power from both lead 326 and lead 332.

FIG. 6 shows the wiring running from the terminal blocks in the controlpanel 72 through the cable 70 to the components in the model 20. Thecable 70 is of 24 lead telephone type. An amphenol plug 334 having afemale part with 24 sockets and a mating male part with 24 prongsprovides a means for disconnecting the control panel 72 from the model20. Only the female portion of the plug 334 is illustrated and the leadsto the components are shown as emanating from the sockets therein, butit is to be understood that this is only for purposes of illustrationand in actual practice the leads to the components are connected to theprongs which fit into the sockets.

FIGS. 7 to 9 show some of the various types of missiles which can befired from the model submarine described herein. FIG. 7 shows a singlestage missile 338 having a tubular main casing 340, a lower nozzleportion 342, a fuse 344 and propellant 346. The main casing can be madeof a rifle shell such as a 3030 or a 30-60 rifle shell, or it can bemade of alipstick tube or other suitable tubular member. The propellant346 can be any suitable composition such as rough grain rifle powder,actual rocket fuel or the like. A very powerful propellant which hasbeen used in these missiles is made by crushing one Jaytex propellanttablet and mixing it with an equal weight of Du Pont 4F Grade blackblasting powder, rough grain. The fuse 344 extends through the nozzleand into contact with a Glo-plug 132, which when actuated will heat thetube causing the propellant to ignite and launch the missile. Theoutside of the missile should be lightly greased to facilitate its exitfrom its missile tube.

FIG. 8 shows a two stage missile 348 having a tubular main casing 350and a lower nozzle portion 352 similar to the missile of FIG. 7.However, the missile 348 is provided at its upper end with a separateportion 354 which constitutes the second stage of the missile. A fuse356 is provided for the first stage and a second separate fuse 358 isprovided for the second stage. Propellant 360 is provided for the firststage in the casing 350 and propellant 362 is provided for the secondstage in the second stage portion 354. The propellants can be of thesame or of different compositions, such as any of those described forthe missile 338. A .22 caliber rifle bullet with its bottom out off hasbeen used effectively as the second stage portion 354. When the fuse 356is ignited by a Glo-plug 132, it will cause the propellant 360 to ignitethus launching the missile. At some point in flight the propellant 360will ignite the second stage fuse 358 which in turn will ignite thesecond stage propellant 362 thus causing the second stage portion 354 toseparate.

The missile described in FIGS. 7 and 8 are extremely powerful and canattain a height of several hundred feet depending upon the size of themissile. Consequently, it will be appreciated that these missiles shouldonly be fired outdoors. Occasionally, however, it may be desired todisplay and demonstrate the model submarine 20 indoors in which case asafe embodiment of missile is needed. Such an embodiment is shown inFIG. 9 as 364. The body 366 of the missile is formed of styrofoam,sponge rubber or some other suitable soft material. A carbon dioxidecartridge 368 is inserted in the body portion 366 with its neckextending out at the bottom end of the missile. The carbon dioxidecartridge 368 provides the motive power to launch the missile 364.

In order to launch the missile 364, a modified system of launchingequipment is needed. The Glo-plugs 132 must be unscrewed from the lowerends of the missile tubes 130 and replaced by threaded fittings 370.Each threaded' fitting 370 has an upper shoulder 372 upon which the baseof the missile rests and an internal shoulder 374 upon which a coilcompression spring 376 rests. A piercing means 378 in the form of aneedle or pin passes through a central aperture in the fitting 370. Thepiercing means has aflixed to it a collar portion 380 of approximatelythe same lateral extent of the internal shoulder 374. The upper end ofthe spring 376 bears against the underside of the collar 380 and therebyurges the piercing means 378 upwards.

A right angle portion 382 of the piercing means 378 extends beyond thelateral extent of the missile tube 130 and is held down under the raisedportion of a cam 384, thus compressing the spring 376, as shown. The cam384 is connected through a gear reducing means 386 to a DC. motor 388.This motor is supplied with power from the lead which supplied power tothe Glo-plug 132 for that tube. When a particular missile tube is fired8 by the operator, the motor 388 turns the cam 384 thus releasing theright angle portion 382 of the piercing means 378 and thus allowing thespring 376 to urge the piercing means 378 upwards. When the piercingmeans 378 punctures the neck of the cartridge 368, the missile 364 willfire.

It is possible to supply other components and equipment to the modelsystem described hereinabove. For example, a small working model of thesubmarine, having indicating lights therein could be furnished on top ofthe control panel 72 so the operator could get a further indication ofwhat is occurring at the submarine, particularly if the submarine issubmerged.

It will be understood that various changes in the details, materials,steps and arrangements of parts, which have been herein described andillustrated in order to explain the nature of the invention, may be madeby those skilled in the art within the principle and scope of theinvention as expressed in the appended claims.
